Re: add hyperlink to mysql results in php

If in the database it says http://www.google.com then the code

echo '<a href="'.$row['website'].'">'.$row['website'].'</a>';

should produce

<a href="http://www.google.com">http://www.google.com</a>

Look at the source (CTRL+U in Firefox) and see if that is what it is producing

Re: Recommendation?

Personally I've never picked up a book on PHP and I wouldn't really recommend it. Books take too long to update and are most likely contain outdated information by the time they're published. Especially when dealing with the web. There will be no better source of information for you than the web (along with php.net)

Re: Writing to Text file: no duplicates

Hi thnx for replying
ShawnCPlus, using your script am still getting duplicates- all in one line.
Acute- I tried the endoffile as well but is not working.
Not sure what else to try, any more thoughts...
Cheers

For future reference here when you say you tried an example and it didn't work post the code otherwise we don't know what we or you did wrong to fix it. If I had to guess I would say that when you're writing to the file you're not appending a newline.

Note: This is beating the crap out of the problem and will be SLOW for large files.

$file = file('somefile');
$FirstName = $_POST['FirstName'];
$LastName = $_POST['LastName'];
$Email = $_POST['Email'];

$line_count_pre = count($file);
$content= $FirstName . '|' . $LastName . '|' . $Email;
$file[]=$content;
$line_count_post = count(array_unique($file));
unset($file);
if($line_count_post > $line_count_pre) {
  // write to the file
} else {
  // It is a duplicate

Re: Pass the array

A) I'm not sure why you don't want to use a session. B) So you're not sending a string too long you could base64encode a json_encoded array and send it through GET.

ie.,

<?php
$some_array = array('blah', 'blah2');
$some_arrayGET = base64_encode(json_encode($some_array));
?>
<a href="somepage?some_array=<?php echo $some_arrayGET ?>">BLAH!</a>

Then on the other side

$some_array = json_decode(base64_decode($_GET['some_array']));

But, as with anything sent over GET (or POST) it can be modified by the user. If you store it in the session it cannot be modified by the user.

Re: how to make a dynamic family tree using php

Actually, 1 and 3 would be combined since the database would be the store for the binary tree. A binary tree works like this

A
        /   \
       B     C
      / \   / \
     D  E  F   G

Where each letter represents a node. Each node has a parent save the top node (A), also called the root. Any node that has a parent but doesn't have children is called a leaf. (In CS trees are upside down if you didn't notice)

Re: Form mail, how to make it work?

A few observations:
1. When you post code, you should use [code] tags to have it format properly.
2. You don't need the <html> <head> and <body> statements. PHP takes care of that.
3. $subject on line 16 isn't defined (at least in what you have shown us).
4. The default is that mail doesn't actually get sent from the local (test) environment. It can be done but you will have to make some changes (if you need this, I'm sure that you can find references from an internet search).

heh, I'm not sure what strange auto_prepend_file setting you're using but PHP does NOT automatically insert any HTML tag.

WAMP/XAMP does not come with an SMTP server so you'll have to configure the php.ini file to point to another SMTP server.

And as noted before, you haven't set the $subject variable to anything.

Re: Disabling CTRL-N in IE7

Well, my first question would be why disable CTRL+N? That still leaves CTRL+T (new tab in ie7) and it doesn't prevent them from just opening a new instance of IE7 the normal way. I personally despise when people alter my keyboard shortcuts and/or disable things on a site. If you're doing this it usually means you've designed something wrong previously and you're trying to make up for it.

Re: PHP-MySQL question

If it returns 0 rows but there isn't an error than its just that. Nothing matches the conditions you're giving it. Trying making your condition less specific until you get a result and then narrowing it down again. Ie.,

Then

SELECT ZipCode FROM zips 
  WHERE Latitude BETWEEN '$swlat' AND '$nelat'
  ORDER BY Population DESC LIMIT 5

Set the cookie

That is correct, you're not lost. You get

from print serialize($data); and you get Array from echo $next As a side note, don't mix echo and print, there's no reason to, they do the same thing.

Well if you want to implode the values and store it in the cookie then you'd explode it to retrieve it as an array.

$string = implode(',', $array); // 'orange,green,blue'
$second_array = explode(',', $string); // array('orange', 'green', 'blue');

Re: Software for PHP

I agree. The tool does not make you good at using it. However, IDE's and editors that provide functionality such as syntax highlighting, etc. are a net positive in productivity for development, especially for large projects. Knowing some of an API (you certainly aren't going to know all of them) by heart doesn't make you a good developer either. If productivity is your main goal, intentionally not using tools that increase it just because you consider them a crutch is ridiculous. As a developer, my employer is much more concerned with how much quality work I can get done rather than how I would fare on a pop quiz on the order of parameters for some random method in some API.
I too have used Notepad to edit code before. I certainly wouldn't argue that it can edit text and will do for a quick change or in a pinch. I highly doubt you are going to argue that it is your preferred tool for writing code and that is the whole point of this thread. I think everyone already knew that any simple text editor could be used. So really it's a question of which editor do you prefer for PHP? Which has features that you find useful and add to your productivity? That's much more germane here than another "bah, a real coder just uses a text editor!" speech.

Heh, we've driven so far off the OP's question we're on a different continent here. The original question …

Re: Software for PHP

Some companies will let you use your platform or IDE of your choice, other doesn't. Some software factories in Argentina aren't well equipped or better than India or Pakistan ones. Old computers running a buggy and sluggish outdated version of Eclipse, with spyware, keyloggers, testing code over old and overloaded instances of Tomcat on servers with a nice trade mark (and some spider web dissimulated), you don't want to know what are happening outsourcing to third-world :)
Work environment doesn't make you justice but you can be good indeed, using any IDE.

Re: Software for PHP

There aren't any drag&drop IDEs for PHP that I know of since PHP itself never touches the front end. Zend Studio is probably one of the best out there (You can download a free version though there is a paid version), there's also the PDT project which is a extension onto Eclipse (Much like Zend Studio)

If I could make a recommendation I would shy away from any editor that does everything for you. You don't actually learn the language if you use an IDE that holds your hand the entire time. In the end if you are somehow left without the IDE you are crippled as a developer since you don't know how to use it otherwise which is a huge problem with PHP.

Re: insert data where

If you're trying to modify an already existing row take a look at
UPDATE which can take a WHERE clause

There is also REPLACE. It acts like INSERT but if a row exists with the same primary key, it will replace it.

IE.,

INSERT INTO sometable (id, name) VALUES (0, 'Shawn');

Will give you the table

ID         Name
0          Shawn
REPLACE INTO someTable (id, name) VALUES (0, 'Tester');

You now have
